Kitty litter in the compost?

Question THIS doesn’t exactly count as a plant problem, but can dog and cat poo be added to the compost heap? And what about used kitty litter? Will it be too acidic?


Answer  IN theory you could add pet excrement to the compost heap but for health reasons it’s not a good idea. There’s too much risk of getting faecal contamination when handling the compost or working in the garden.

The best thing to do with pet poo and kitty litter is bury it in the garden (not the vegetable garden) and allow nature and soil organisms to deal with it. Or flush it down the toilet.
